Baião","doi":"10.1201/9780429424441-470","DOIUrl":"https://doi.org/10.1201/9780429424441-470","url":null,"abstract":"Last year the Portuguese Public Procurement Code was reviewed and republished by Decree-Law 111-B/2017, which transposed the European Directives 2014/23/EU, 2014/24/EU, 2014/25/EU and 2014/55/EU into Portuguese legislation. The reviewed code came into force in Portugal on January 1st, 2018. This article focuses on the most relevant changes related to Subsurface Contracts for Complex Geotechnical Works. A brief summary of the changes that impact directly the design, tender, execution and risk management of subsurface works (especially for tunnels) is presented. The article also promotes the best international contractual practices recommended by the International Tunnelling and Underground Space Association (ITA). In a second step, the potential appliction of these practices in Portugal will be highlighted and limitations and opportunities will be discussed. 2 BRIEF BACKGROUND ON THE NEW EU PUBLIC PROCUREMENT DIRECTIVES AND SUBSURFACE PROJECTS 2.1 The new EU Public Procurement Directives On 26 February 2014 three new public procurement Directives were adopted by the European Parliament and the Council of the European Union: Directive 2014/24/EU on public procurement (known as the ‘classic directive’), Directive 2014/25/EU on procurement by entities operating in the water, energy, transport and postal services sectors (the ‘sector specific directive’), and Directive 2014/23/EU on the award of concession contracts. Those directives had to be transposed by EU countries into national law by 18 April 2016. EU member states have stepped up their efforts to implement those new procurement directives, and despite some delay, by the end of 2017 almost all countries (with just four exceptions) have made that transposition, Portugal included. The 2014 EU public procurement reform pursued several objectives, in order to achieve EU strategic policy goals while ensuring the most efficient use of public funds: i) make public spending more efficient; ii) clarify basic notions and concepts to ensure legal certainty; iii) make it easier for SMEs to participate in public contracts; iv) promote integrity and equal treatment; v) enable contracting authorities to make better use of procurement in support of innovation and common societal and environment goals; and vi) incorporate relevant case-law of the Court of Justice of the European Union. The new Directives have introduced a number of changes and new rules in order to simplify public procurement procedures and make them more flexible. For instance, a key aspect of the new directives concerns the article 72 of the 2014/24/EU directive (modification of contracts during their term) that clarifies in which cases contracts and framework agreements can be modified without going through a new procurement procedure, and in which cases a substantial change leads to a retendering of the contract. One example: for additional works (services or supplies which were not included in the original contract) the directive provides ","PeriodicalId":69598,"journal":{"name":"地下工程与隧道","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82116352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ramesh","doi":"10.1201/9780429424441-583","DOIUrl":"https://doi.org/10.1201/9780429424441-583","url":null,"abstract":"Singapore Metro system has been developing in recent years to enhance the connectivity of existing network Mass Rapid Transit (MRT) system. Currently, there are 5 lines across the island in operation – North South Line (NSL), East West Line (EWL), Circle Line (CCL), North East Line (NEL) and Downtown Line (DTL). In addition, Thomson-East Coast Line (TEL) is under construction and 2 more lines – Jurong Region Line (JRL) and Cross Island Line (CRL) – are under planning. This increased connectivity has resulted in a more complex train network, which in turn poses greater construction risk of tunneling under or above existing lines. Contract T222 involves the construction of Outram Station and the TEL tunnels. The Outram Station will become an interchange connecting 2 existing lines in the Central Business District (CBD) located between Havelock Station (HVL) and Maxwell Station (MAX), overcrossing the existing NEL and undercrossing the EWL tunnels. One unique aspect of T222 is that the tunneling works undercrossing the EWL tunnels are in parallel for about 365m for both the tunnel drives with a clear distance ranging from 1.8m to about 8m.This is the first time such a tunnel drive is planned in a urban district with some complex geology under the ground water table. Being within the urban district, there were numerous challenges to be encountered. One key challenge was to manage the stakeholders and to control the excavation to ensure that there was no over/under excavation that would impact the live tunnels. One another key challenge was to mine under the water table which was the sensitive criteria as drawdown could also cause movements to the tunnels and in addition managing the same water during the interventions was another concern. This paper discusses the approach of tunneling for the undercrossing of the EWL tunnels, key tunnelling parameters used, stakeholder management and coordination, instrumentation arrangement, monitoring as well as the challenges faced and opportunities for future application.","PeriodicalId":69598,"journal":{"name":"地下工程与隧道","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87492111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
